In the XMOS Audio aspect, Singxer takes the lead in developing the XMOS second-generation xCORE-200 series processors, At the same time, in the hardware architecture, Singxer self-developed clock system,independent to development of digital phase locked loop technique "SHDPLL", I2S shaping technology, and the isolation technique.

 

su-6 digital interface 

 

With the popularization of digital music streaming, digital interfaces and decoders are indispensable. Most DACs do benefit from being paired with high quality USB converters, often sounding significantly better compared to a direct connection to the DAC's USB input. And Singxer is praised by it's high-performance USB digital audio interface like SU-2, SU-6. Singxer also released their new flagship SDA-6 AK4499 XMOS XU208 DAC in July, 2020. 

 

As a high-end USB interface, the SU-6 uses XMOS' latest xCORE-200 series and Xilinx's high-performance large-scale PGA chip and utilises two Crystek CCHD low phase noise Femto second clocks. These clocks are contained in a metal enclosure for temperature stability. It offers offers a high level of information retrieval, with a silky and refined top-end and controlled bass with the right amount of tightness and bloom.The SU-6  Midrange is more laidback and richer, but is still detailed and textured, will not get the feeling of information being smoothed over.
